摘要：In this article, two methods are proposed to give the interval estimation for two parameters Log- Normal distribution. We usually use traditional method to construct interval estimation. This interval needs a t distribution and chi-square distribution and namely traditional method. We will use another method, namely bootstrap percentile. Bootstrap percentile method more potential in constructing two parameters interval and give shorter interval than traditional method. This method does not need an assumption that the sample has to have t and chi-square distributions.
